Description of drawings
Fig. 1 is the structural representation of interior return channel device of the present utility model;
Fig. 2 is the vertical view of the return channel in the device shown in Figure 1.
The specific embodiment
Below in conjunction with specific embodiment, and, the utility model is described further with reference to accompanying drawing:
The utility model is the recirculation control device that is used for the operation of the small-sized stainless steel rectifying in laboratory reflux in tower.Its structure is that vertical type condenser tower head is set on the top of rectifying column, also refluence control device parts of the present utility model must be installed between tower head and cat head in addition, promptly interior return channel.
Interior return channel device as illustrated in fig. 1 and 2, return channel 3 and the vertical type condenser 1 that is arranged on described interior return channel 3 tops in it comprises.Backflow cylindrical shell in return channel 3 comprises in described, in described, be disposed with umbrella crown structure 2 in the backflow cylindrical shell from top to bottom, pendulum funnel 5, fluid cylinder 10 and backflow collector tube 12 are received in extraction, described umbrella crown structure 2 comprises the gripper shoe that links to each other with interior backflow cylindrical shell, have circular hole at described gripper shoe middle part and hang with the umbrella crown that is umbrella shape by bracket leg, described gripper shoe is connected with the inlet of a condensate liquid mozzle 16 that is obliquely installed by the return port of opening on gripper shoe, the outlet of described condensate liquid mozzle 16 be arranged on pendulum funnel 5 directly over, the bottom of described pendulum funnel is connected with funnel down-pipe 6, facing on the lateral attitude of funnel down-pipe iron core and solenoid 8 are installed at interior backflow cylinder body outer wall, solenoid 8 lead-in wires are connected with backflow controller 9, with the funnel down-pipe side-walls of described iron core relative position throw-out lever 7 is installed, described extraction receipts fluid cylinder is installed in the bottom sides of funnel down-pipe and is provided with at interval with described interior backflow cylindrical shell, the outlet at bottom that fluid cylinder 10 is received in described extraction is connected with the inlet that an outlet is arranged on the extraction discharging tube 11 of described interior backflow cylindrical shell outside, the outlet of described funnel down-pipe 6 be arranged on backflow collector tube 12 top inlet directly over, backflow cylindrical shell top is inserted with temperature-measuring casing 4 in described.Described vertical type condenser 1 is arranged on interior backflow cylindrical shell top.
The cross section that fluid cylinder is received in preferred described extraction is semicircle.Described backflow collector tube is an infundibulate.
The symmetry axis of preferred described condensate liquid mozzle and the angle of vertical direction are the 10-15 degree, and changing direction like this to flowing downward has good effect.
The cross-sectional area of the circular hole at preferred described gripper shoe middle part is the 55%-65% of interior backflow cylindrical shell cross-sectional area, like this rising steam is had good effect.
The diameter of preferred described interior backflow cylindrical shell is 1.2-2 a times of rectifying Tata diameter, so high capacity of returns is had good effect.
The principle that adopts this return channel to carry out interior reflux operation is: (bottom of tower 13 is provided with tower still 14 at rectifying column 13, in tower still 14, be provided with heating member 15) in uprising gas enter vertical type condenser 1 by interior return channel 3, condensed liquid flows into the pendulum funnel 5 that can swing through subcooling condensate mozzle 16, funnel down-pipe 6 usefulness magnetic stainless irons are made, in the bottom of interior return channel 3 backflow collector tube 12 is arranged, collection liquid is all got back in the tower, when the pendulum funnel is not swung, be infinite reflux.In the side of funnel down-pipe 6 a semicircular extraction is installed and receives fluid cylinder, receive liquid causes the return channel outside by extraction discharging tube 11 extraction liquid collecting tank.Facing to iron core and solenoid 8 are installed on the lateral attitude of funnel down-pipe, the solenoid lead-in wire is connected with backflow controller 9 at interior backflow cylinder body outer wall.This instrument is the iron core carrying magnetic when giving electricity, and then the funnel down-pipe is drawn in the semicircle extraction receipts fluid cylinder, and the extraction discharging tube is arranged at the bottom that fluid cylinder is received in extraction, passes barrel wall and is connected with outside, and liquid is flow to outside the return channel.When changing the value that the adhesive of backflow controller can change reflux ratio conduction time, the extraction of promptly switching on, power failure reflux, and the ratio of time is reflux ratio.
This backflow controller be applicable to the tower diameter at all towers such as the stainless steel helices tower of 20-100mm, sieve-plate towers, also be applicable to the normal pressure that the laboratory of all towers of glass rectifying column uses, decompression, pressurization, continuously, the operation of batch fractionating tower.Interior return channel diameter is 1.2-2 a times of rectifying Tata diameter.Pendulum funnel and semi-circular extraction are received the fluid cylinder size and are increased and decreased by the tower vary in diameter, do not overflow in funnel and in the extraction receipts fluid cylinder with the amount of whole liquid that reflux after the condensation of maximum rising steam and exceed.The gap that must leave a small amount of (can be 1.5-2.5mm usually) between fluid cylinder and the interior backflow cylinder inboard wall is received in extraction, receives in the fluid cylinder to prevent that liquid from flowing into along the backflow wall, causes extraction and backflow ratio undesired.
